I've used WordPress for several years now and this is the first time I'm experiencing problems with the plugins.
Last night I installed the "Google (XML) Sitemaps"-plugin and it worked great. Today I wanted to install Matt's Random Page-pluing and it doesn't show up in my plugin dashboard. I try to upload another plugin - same problem.
Then I try to delete and old plugin - it disappears on the dashboard, as it should, I re-upload it, but it doesn't reappear on my dashboard.
I can active and deactivate plugins just fine.
Thank you in advance for any help and answers.
